WebIn 1933 low density polyethylene (LDPE) was the first type of polyethylene to be synthesised. LDPE has more branches than HDPE, and the branches are long. Because of this chain configuration the molecules cannot order as well as with the linear HDPE chains, and the crystallinity is lower. This is the reason why the density of LDPE is lower than ... Shear stress (often denoted by τ (Greek: tau)) is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts.
